Ferrites can be sold as scrap as stated here. They are made of a combination of zinc and iron or magnesium and iron powders pressed together. I'm not sure they are a true ceramic. They are around the monitor chokes and also as donut or tube shapes around wiring in monitors and most compute equipment. Sometimes they are painted and often rubber sheathed. The ferrites around wires are selleable RF chokes to electronics hobbyists. They are sold as shreddable steel scrap in general. If a scrapyard questions you having them in your load simply tell them to check them with a magnet. Their rule is if it is magnetic it has to be scrap steel or iron.
Also shown in the photo of the power supply board are small copper transformers on the board which can be popped off. A couple in this photo are wrapped in yellow tape. They are can be sold to some scrapyards as low grade copper scrap. The current pricing is around 20 to 25 cents a pound, sometime higher but don't assume every scrapyard takes them. You need to ask first. I have about 15 scrapyards withing 60 miles of my house and only three of them take them. Regards, Chris Hyder.
